4 Claims.

The present invention relates to new and useful improvements in closures for containers, such as bottles, jars or the like, and more particularly to improvements in a double shell cap which has attached thereto a dauber or applicator for applying the contents of the container.

An object of the invention is to provide a double shell cap of the above type, wherein the dauber shank is secured between the inner and outer 1'0 the dauber shank is in the form of a wire extending through the inner shell and coiled to lie between the inner and outer shells.

A still further object of the invention is to provide a double shell cap of the above type, wherein the coiled end of the dauber shank is positively held against rotation relative to the cap.

A still further object of the invention is to provide a double shell of the above type, wherein the inner shell is provided with a recess in which the coiled end of the dauber shank is seated and maintained by the outer shell.

The invention still further aims to provide a double shell cap of the above type which may be conveniently and inexpensively manufactured, and which is adapted to seal the container.

The above and other objects of the invention will in part be obvious, and will be hereinafter more fully pointed out.

In the accompanying drawing,

Figure 1 is a side view, in section, showing the improved double shell cap and dauber applied to a container.

Figure 2 is a top view, in section, taken substantially along the line 22, showing the coiled end of the dauber shank in position with respect to the inner shell.

Figure 3 is a bottom view, in section, with the sealing gasket and outer shell removed.

Figure 4 is a detailed view, in section, showing the connection between the dauber shank and the inner shell.

In furnishing certain fluids, such as shoe polis or the like, it is desirable to afford some means for facilitating the application of the polish or other material. In order to guard against the loss or misplacing of separate brushes or spreaders, the present invention contemplates the securing of a dauber or applicator directly to the cap for the container. The cap is of the double shell type wherein the outer shell presents a smooth and even surface and wherein the inner shell may be threaded to engage corresponding threads on the container end. The dauber is carried by a shank extending within the container and the upper end of the shank is secured between the inner and outer shells and positively held against rotation or disengagement therefrom. Thus, the cap serves as a handle for the dauber so that when the cap is removed, the polish or other material may be applied to any desired surface.

Referring more in detail to the accompanying drawing, the container I0 is illustrated as being in the form of a glass jar having a neck portion I! provided with external threads l2. The container serves as a receptacle for the polish or other material to be furnished.

The cap is of the double shell type and includes an outer shell [3 and an inner shell H4. The outer shell I3 presents a smooth exterior surface and is provided with a depending skirt portion I5, the lower end of which is curled inwardly, as at Hi, to grip the lower end of the skirt portion ii of the inner shell I4. Thus, the inner and outer shells are prevented from rotating relative to one another. The skirt portion ll of the inner shell I4 is threaded to cooperate with the external threads 12 on the neck portion of the container.

The end portion of the inner shell M is provided with a substantially circular recess or groove I8, one end [9 of which is closed and the other end 20 of which is apertured. The dauber 2i may be of any suitable material and is attached to a shank 22 which extends through an inner sealing gasket 23. The edge portion of the sealing gasket 23 is pressed between the inner shell I4 and the edge of the neck portion l I so as to effect a sealing of the container when the cap is screwed thereon. In the space between the central portion of the gasket 23 and the inner shell [4, the shank 22 is bent at right angles, as at 24, to extend to a position between the closed and open ends I9, 26 of the recess IS. The shank portion is then bent to enable it to pass into the aperature at the open end of the recess l8. The end portion 25 of the shank 22 is bent symmetrically with respect to the curvature of the recess l8 so that it will snugly fit therein. The end portion of the outer shell I3 serves to maintain the coiled end 25 of the shank 22 properly located in the recess 18. The closed end 19 of the recess l8 serves as an abutment for the portion 24 of the shank 22 in order to prevent rotation thereof. An annular sealing gasket 26 is disposed between the inner and outer shells substantially at the junction between the end and skirt portions thereof in order to guard against the leakage of any material which may gain access to the space between the two shells.

From the foregoing description, it will be seen that the present invention provides an efiicient and substantially rigid connection between the.

double shell cap and the shank 22 which is in the form of a wire. The end of the outer shell and the recess It] in the inner shell are shaped to provide a space, within which the coiled end 25 of the dauber shank is housed and maintained. For convenience in assembling the cap and dauber, the wire shank 22 may be passed through the. inner liner or sealing gasket 23 before the end 25 thereof is coiled. After the end of the shank 22 is properly shaped and coiled, the free end of the portion 25 is threaded through the apertured end 28 of the recess l8 and turned so that the coiled portion will fit Within the recess and .the right angled horizontal portion 24 will lie between the closed and open ends 19, 20, respectively, of the recess. Thus, the dauber shank is prevented from turning relative to the cap. The coiled end portion 25 is maintained seated in the recess 18 by the outer shell 13, and any eifort to remove the dauber shank from the completed cap will be prevented. The inner gasket 23 serves to prevent bendingoi the horizontal portion 24.

It is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the scope of the invention as set forth in the appended claims.
